What is the Coin Flip?

Coin Flip gives you a fair 50/50 random outcome — Heads or Tails by default, or any two labels you set (e.g. "Pizza" / "Burgers", "Yes" / "No"). Cryptographically random, no signup, no real-money games — just a clean tool for casual decisions and tiebreakers.

How to use it

Leave the labels blank for a classic Heads / Tails flip, or type two custom labels.
Tap "Flip the coin" — the result reveals after a quick animation.
Tap again for another flip; share the page URL to send a friend the same setup.

Common use cases

Frequently asked questions

Is it really 50/50, or does it favor heads?

Exactly 50/50. The flip uses cryptographic rejection sampling, which means each side has exactly 50.0% probability — no favoring of heads, no bias toward whichever side you flipped last. The same RNG primitive powers every Plinkr random tool, so the fairness guarantee is consistent across the site.

Can I link to a specific flip result to show someone?

Yes. The result lives in the URL state after a tap, so you can copy the address bar and send the link to anyone. They will open the page and see the same coin already flipped to the same result. Useful for settling "did the coin really land on heads?" disputes — proof in URL form, no screenshot editing required.

Is this for gambling or sports betting?

No. Plinkr is for casual decisions only — settling who pays for coffee, who picks the show, who goes first. There is no real-money mode, no payout, no integration with any betting platform. The phrase "coin flip" overlaps with gambling search intent, but Plinkr's tool is firmly on the casual-decision side of that line.

Is each flip recorded anywhere, or is there a flip history?

No. Each flip happens entirely in your browser; nothing is sent to a server, no log is kept. The flip result is in the URL state on your tab, but that URL is local to you until you copy-paste it somewhere. There is no Plinkr account, no flip history, no "recent flips" feed visible to anyone.

How is this different from "decide for me" on the Yes or No tool?

Coin Flip's "decide" is for two named options between which you're truly indifferent — Pizza or Burgers, this restaurant or that. Yes or No's "decide for me" reframes a "should I" question into a Yes/No/Maybe verdict. Different formats for different question shapes: binary chance vs verdict-for-reframing.

Can the labels stay set across multiple flips in a row?

Yes. Type the labels once, tap Flip as many times as you want — the labels don't reset. Useful for multi-round decisions: "first to win three flips picks the movie" or similar. Each flip is independent (past flips do not influence future ones), but the labeled UI persists across the whole session.

Does the URL change so I can share the labeled flip?

Yes. After a tap, the labels are encoded in the URL as query parameters (a=Pizza&b=Burgers). Copy the address bar and send the link — the recipient opens to the same labeled flip already set up. Useful for asynchronous decisions where the other person flips on their own time.

Is this for gambling — settling bets between two outcomes?

No. Plinkr is for casual decisions only — settling who picks the show, who pays for coffee, which of two options to choose tonight. There is no real-money mode and no integration with any betting platform. Decisions where the cost of either side is roughly equal and small are the right fit; financial wagers aren't.

Why type names instead of just using heads or tails?

Custom labels make the result self-explanatory. "Heads" does not tell you who is first; "Maya" does. With two names typed into the labels, the flip output reads back as a verdict — no need for the side discussion of "OK, you were heads, so heads goes first." This is the difference between a generic coin flip and a tool actually built for the question "who goes first."

Is the flip really 50/50, or does it favor the first label?

Exactly 50/50. The flip uses cryptographic rejection sampling under the hood — each label has the same probability regardless of the order you typed them in, the length of the names, or anything else about the input. The same code base powers every Plinkr random tool, so the fairness guarantee is consistent across the site.

Can I use the same setup for multiple rounds in a single sitting?

Yes. Each tap of the flip button is independent — past flips don't influence future ones. For a best-of-three or a multi-game evening, just flip again before each game. The labels stay set across flips, so you only type the names once at the start of the night and reuse the same setup all evening.

When should I use random-picker instead of coin-flip?

For exactly two options, use coin-flip. The random-picker is built for lists of three or more — picking from a class roster, a giveaway list, or a menu of restaurants. With two options, coin-flip's UI (a single fair flip with custom labels) is the better fit. Three players or more? That's where random-picker shines.

Why use a coin flip instead of voting again?

Once a group is split evenly, a re-vote often produces the same split — most people don't change their minds under social pressure. A pre-agreed coin flip resolves cleanly without forcing anyone to switch positions, and the procedural legitimacy of "we agreed to abide by this" prevents litigating the result afterward.

Should the group agree to the flip outcome before flipping or after?

Before. The entire point is pre-commitment — everyone signs up to the random process before the flip happens. Agreeing afterward defeats the procedural legitimacy: "we will abide unless we don't like the result" reduces to no resolution at all. Tap once everyone has explicitly committed; the flip then closes the discussion.

Can I use this for political votes or binding workplace decisions?

No. This is for casual social and small-group use — friend groups, project teams, family decisions where the stakes are low. Political votes have ballot procedures; binding legal arbitration has formal processes. A random verdict is appropriate when the cost of either outcome is low and procedural fairness is the goal, not when actual evidence or law applies.

Is the flip itself recorded as proof of the procedure?

The labels and result are encoded in the URL after a tap, so a copy-paste of the URL produces a shareable link to that specific flip outcome. The page itself doesn't store flip history server-side — there's no Plinkr account, no audit log. The URL is the record. Send the link to the group as the procedural artifact.
